Pathogenicity of Xiphinema chambersi on Sweetgum. John L. Ruehle, Principal Plant Pathologist, Forestry Sciences Laboratory, Southeastern Forest Experiment Station, Forest Service, USDA, Athens, Georgia 30601; Phytopathology 62:333-336.

Seedlings of Liquidambar styraciflua were stunted severely when grown in the greenhouse in soil infested with Xiphinema chambersi. These nematodes parasitized the seedlings and multiplied, and their feeding resulted in malformed and necrotic feeder roots. Root and shoot weights and height of seedlings grown in infested soil were significantly less than those of seedlings in noninfested soil.
